how can SEl deliver all these features for only $960?

By leveraging successful designs for relays and automation controllers with world-class manufacturing. And not by cutting corners on quality.

what if I burn out a relay contact in a DPAC?

First, SEL has a ten-year, no-questions-asked warranty. If you burn out a contact, SEL will repair your DPAC usually within 72 hours. Second, the DPAC is entirely connectorized, so you can easily remove it from service without removing any wires from the connectors. Because of the low price, having a spare on hand for only $960 is affordable. Simply download your settings to the spare and insert the connectors for a fast, simple, and economical repair.

Can I expand the I/o of the DPAC?

Yes! The base product typically has 32 inputs and 16 outputs. Want some more? You can add two SEL-2505 Remote I/O Modules (8 in/8 out), one per serial port, for a total of 32 more points. . .for a grand total of 80 I/O points! But, the DPAC is so cost effective to begin with, it’s usually most economical to buy another DPAC! Remember, it’s $20 per point for protection quality I/O.

where is the DPAC designed and made?

It is designed and manufactured in our factory in Pullman, Washington. The DPAC firmware was developed by SEL in Pullman too.

Can I hook two DPACs back-to-back? what kind of performance can I get?

You may be familiar with our SEL-2505 Modules. They communicate 8 points in each direction, so that 8 inputs at one end are 8 outputs at the other, and vice versa. You can do exactly this with 8 inputs and 8 outputs of each DPAC and still have your other I/O. End-to-end delay is about 7 ms. Or, you can use IEC 61850 GOOSE messaging and the Ethernet ports to communicate any desired combination of I/O points; e.g., 16 inputs to 16 outputs one way and 8 inputs to 8 outputs going back.

how can I apply the DPAC in my system?

You can use it as a standalone controller or digital concentrator. Or, you can use the DPAC as a host or I/O expansion for the SEL-2411 Programmable Automation Controller (PAC) that also supports low-level dc or ac analog inputs. For automation and control applications, you can use the SEL-3530 RTAC or our embedded computers. You can also connect your DPAC to SEL-2020, -2030, -2032 communications processors via our SEL protocols, or easily integrate with your existing SCADA infrastructure with DNP3 and Modbus® protocols over Ethernet or serial connections.

this is a new product for me. how can SEl assist me?

If you are already familiar with the SEL-2411 PAC, then you will be right at home with the DPAC. They have the same roots. The DPAC is actually easier, because it doesn’t need to handle analog signals. If you have never used an SEL device, then now is the time! We have field application engineers around the world who are ready to assist you with your designs at no charge. Or, our systems engineering team can develop a detailed custom design for you in accordance with your needs at reasonable fees. Or, if your local consultant wants help, we are prepared to support him or her as well.

your literature stresses that you guarantee performance to various standards. what does this mean?

The design engineers at SEL understand these standards, and they know that their designs must not only comply but also have margin beyond the standard. For instance, standards require a dielectric strength test (HiPot) of 2000 Vac. SEL adds margin onto the standard and requires the product pass at 2500. . .for a 25 percent margin above the standard! This requires careful attention to clearances, spacing, and many other parameters. Unfortunately, there are many devices, costing much more and having (understandably) weaker warranties, that say their products are “designed to” the standards. . .whatever that means. Be assured that when SEL mentions a standard, we meet it! Not only “designed to.” Not only “tested to.” But “tested to and passed with margin!” Standards exist for a reason: these devices are put to work in hostile environments, and you and we need to sleep at night, knowing we have taken every step possible to reasonably assure performance in the substation environment for many years.

Frequently Asked Questions

5

Be Sure your Discrete I/o System measures Up to SEl Safety, reliability, and Economy

DESIgn SEl othErS ImPortAnCE

Positive retention of connectors � no

Control wiring is stiff and heavy. Connectors without positive retention can come off, causing failure or misoperation of your control system.

2000 V all circuits to ground � ??

Faults can stress power supply and I/O to high voltages. Flash-over can destroy I/O and cause misoperations.

2000 V circuit-to-circuit � ?? Adjacent circuits can have different references.

HiPot routine test � ??

Every SEL device is HiPot tested in manufacturing before it goes out the door. Others may not be and may fail during HiPot testing of your panels.

Utility-rated power supply � no

SEL makes its own power supplies, which have a 600-year MTBF. Others may use commercial supplies, as found in computers.

AC/DC inputs � no

SEL inputs are dual-rated. Others are typically dc only. AC-rated inputs are needed for monitoring ac loads and volt-age transformers.

Level-sensitive inputs � no

SEL input thresholds are near one-half the battery voltage to prevent false assertions. Others may use “universal” inputs, with thresholds as low as 12 V, which may misoperate on battery grounds, transients, and switching events.

—40˚ to +85˚C � no

The SEL DPAC will work in outdoor cabinets and when air conditioning fails. Others probably won’t.

Vibration � ?? Designed and tested to work in vibration-prone environments.

Tested to IEEE C37.90 � ??

SEL type tests all products. Others may say only “designed to. . .” Type tests prove secure, reliable performance.

ProtoColS

DNP3 and Modbus® � no

SEL recognizes that different applications require one or the other, so we provide both at no additional cost.

IEC 61850 � noSEL supports the international standard for communications and integration in substations.

SEL Fast Message � no Enables easy additions to SEL communications processors.

SEL Mirrored Bits® communications � no Provides high-speed, secure,
